Your making up assumptions. I never said anything about sleeping with lots of women. Talk to 4 women, if they seem interested ask them out. 1/4 should say yes. If they don't seem interested don't ask them out.
Never used dating sites. Using a dating site in Thailand is like going to the beach and calling Grab and asking for a sand delivery. The guys and gals on them probably desperate or full of stds if use a lot.
Should be able to hit a home run with 3 or 4 swings of the bat. If not something is wrong with your approach or you need to see the dentist and choose a better deoderant.
Sometimes it is hot from 1pm 7pm but it isnt going to be cool at 1pm and hot at 4pm. That just doesn't happen. Peak temperatures are usually hit around 1pm and can last a few hours or last longer. This can be looked at on weather sites. If you have alternative evidence that is significant then post it.
11am to 2pm is generally hot in Thailand and you just adapt. 3pm to 10pm are the best hours in Thailand. Breakfast, gym, pool then stay in aircon to 2.30pm then go out do things. That's the way to live.
